When packaging apps for Sandstorm, eradicating these sorts of external dependencies is one of my top irritations. Not only do projects themselves rely on them, but components they drag in also bring in their own CDN dependencies. FontAwesome is the top offender today, call out to a third party server just to avoid hosting your own toolbar icons.
Recently, Sandstorm added the ability to block apps from loading external client-side scripts, and I hope more app platforms and hosting platforms adopt similar so that doing it goes out of style.
